1. The perimeter of a certain isosceles right triangle is 16 + 16sqrt(2).  What is the length of the hypotenuse of the triangle??


What is the answer and how do I solve this question?

Thank you...

昨天模考到了，我还做错了，hypotenuse原来是斜边，我记成高了，高就是height呗？
很简单，等腰直角三角形，周长为16+16√2，也就是(16√2+32)/√2，你能看出来了吧两个腰都是16/√2，斜边就是16√2/√2，也就是16，选B~
